I often think it is just as well I live alone. This morning the window cleaner arrived when I was still in my dressing gown, and I spent the next 20 minutes rubbing the dogs' backs while chanting the "Flappy, flappy, bang, bang" song to distract them from the brush bumping against each of the windows in turn. It works, but is definitely a bit silly! Why is it that silly songs always seem to be more effective than operatic arias?!
